FIELD OF INVENTION

The invention relates generally to utility hand tools. Morespecifically, the invention relates to hand tools used for gardening.This improved hand tool device includes a rotational handle that mayrotate at least between 15 degrees to 125 degrees to help reduce therisk of injury and increase power application when gardening by creatinga favorable angle between the ground and the point of entry of the handtool device into the ground.

BACKGROUND

Gardening requires the use of a variety of tools including hand tools orpower tools. A hand tool is any one of many tools made for gardens andgardening and overlaps with the range of tools made for agriculture andhorticulture. A hand tool is typically ideal when a power tool mightotherwise be impractical or burdensome to use. A hand tool is alsogenerally preferred over larger gardening tools because a hand toolrequires the use of only one hand, takes up minimum space, and is easilystored.

The hand tools still used by gardeners originated with the earliestagricultural implements used by man, for example, the hoe, pitchfork,fork, rake, hand cultivator, spade, shovel and hand trowel. The earliesttools were made of wood, flint, metal, tin, and bone. However, thedevelopment of metal working, first in copper and later in iron andsteel, enabled the manufacture of more durable tools.

Unfortunately, repetitive strain injuries (RSI) can result from the useof hand tools while gardening due to repetitive tasks, forcefulexertions, vibrations, mechanical compression, or sustained positions.RSI is an injury to the musculoskeletal and nervous systems that mayaffect any part of the body and at times at multiple locations, such as,but not limited to, the neck, shoulder, elbow, hand, wrist, and fingers.Repetitive stress injuries can develop over time and can lead tolong-term disability.

According to the National Institute for Occupational Safety and Health(NIOSH), excessive force imposed on muscles may increase the potentialfor musculoskeletal injury and disorder. Furthermore, NIOSH cites anumber of studies what indicate that even less than excessive force maypredispose a person to musculoskeletal injuries and disorders,especially during repetitive activities or static activities performedwith an awkward posture.

Fortunately, several methods of reducing repetitive strain injurieswhile gardening have been developed. Some of the most common techniquesinclude keeping elbows partially bent, especially when doing resistiveactivities requiring elbow strength; avoiding twisting the forearms backand forth repeatedly; keeping wrists in a neutral position; holdingobjects with a light grasp for a short period of time; and squattingwith heels on the ground. While all of these actions can help minimizethe occurrence of repetitive stress injuries, proper hand tools with acomfort and functional design are also necessary for preventingrepetitive strain injuries. In fact, proper ergonomic design isnecessary to prevent repetitive strain injuries and othermusculoskeletal disorders, which can develop over time and can lead tolong-term disability.

Ergonomics is the practice of designing products, systems or processesto take property account of the interaction between them and the peoplewho use them. Ergonomics is concerned with the “fit” between the user,equipment, and their environments. The goal of ergonomics is to design atool so it creates less stress on the body. Ergonomic designs ofequipment, systems, and working methods improve the comfort, health,safety, and productivity of the users.

Conventional hand tools are generally one size fits all. This approachmay be sufficient for most people who use hand tools occasionally. Theinexact fit of the hand tools with the shape and flexibility of thehuman hand causes limited problems.

Some portion of the population use hand tools daily as part of theirhobby or in their chosen line of work, and for these people, the lack ofexact fit to the human hand is causing serious physical injury.Therefore, manufacturers have taken the science of ergonomics andapplied it to garden tools for those gardeners who are constantly usingstill want to be active outdoors even though they might have morephysical limitations. Ergonomic hand tools are designed to keep the bodyin neutral positions while working, lessening the amount of stress onjoints and muscles. Incorporating ergonomic design into hand tools usedfor gardening allows gardeners to work while exerting less energy, sothey can still enjoy all the pleasures and productivity of gardening.

In gardening, ergonomic design not only reduces the risk of injury, butcan also assist with power application. Ergonomic design of hand toolsallows a user to set the angle that best suits them and the job they aredoing. For example, the handle of a hand tool must be held at thesmallest possible angle in relation to the ground, in order to propelmotions, such as digging or lifting, forward as effectively as possible.If the angle between the handle and the ground becomes too large, thebase of the hand tool will make less contact with the ground and willhave a detrimental effect on the desired operation. In essence,effectively adjusting the angle between the handle and the ground allowsa hand tool to exert pressure on a wider area, making the desiredoperations more efficient and easier to perform.

Currently, many hand tools are ergonomically designed with cushionedhandles. Although at first the difference between cushioned andnon-cushioned handles is subtle, over time the reduced strain on handand arm muscles is noticeable. However, a cushioned handle, by itself,may not be sufficient in protecting a user and satisfying all of theergonomic requirements of a user. Moreover, the simple cushioning to thehandles does not assist with or improve on the power application of thehand tools.

Thus, there is a need for a hand tool that will allow a user to lift aperform operations with as much power as possible while minimizing riskof injury. Thus, there remains a need for a hand tool that will offer amore ergonomic design to improve the comfort, health, safety, andproductive of the user.

In the following detailed description of various embodiments of theinvention, numerous specific details are set forth in order to provide athorough understanding of various aspects of one or more embodiments ofthe invention. However, one or more embodiments of the invention may bepracticed without some or all of these specific details. In otherinstances, well-known methods, procedures, and/or components have notbeen described in detail so as not to unnecessarily obscure aspects ofembodiments of the invention.

While multiple embodiments are disclosed, still other embodiments of thepresent invention will become apparent to those skilled in the art fromthe following detailed description, which shows and describesillustrative embodiments of the invention. As will be realized, theinvention is capable of modifications in various obvious aspects, allwithout departing from the spirit and scope of the present invention.Accordingly, the screen shots, figures, and the detailed descriptionsthereof, are to be regarded as illustrative in nature and notrestrictive. Also, the reference or non-reference to a particularembodiment of the invention shall not be interpreted to limit the scopeof the invention.

In accordance with the method and apparatus of the invention disclosedherein, the present invention is an improved hand tool for gardeningwherein the rotational handle may be adjusted at least between 15degrees to 125 degrees with a releasable locking mechanism to allow auser to use and perform operations while minimizing the risk of injuryand increasing comfort and productivity. In one embodiment, the rotationhandle can rotate 360 degrees. In another embodiment, the releasablelocking mechanism allows the rotational handle to rotate 45 degrees at atime. In another embodiment, the releasable locking mechanism allows therotational handle to rotate 30 degrees at a time. In another embodiment,the releasable locking mechanism allows the rotational handle to rotate15 degrees at a time. Specifically, the hand tool device provides for arotational handle, which can adjust to the varying needs of the user,which will create less strain on the hand, wrist, and arm. This isbecause functional capabilities of the hands are important for workefficiency. Hands require a certain level of strength and precision,depending on the type of task being performed. The right combination ofstrength and precision in handling the task involves a delicatemanagement of the sensory system of the hand. Therefore, the presentinvention takes into consideration the anatomical and physiologicalcharacteristics of the hand by providing a rotational handle that canadjust to the user's anatomical and physiological needs depending on thetask the user is seeking to accomplish.

In particular, there is a pin with spring on the surface of the malecomponent and sink holes on the inside bottom part of the femalecomponent. This pin with spring and sink holes combination provide theutility hand tool to be adjustable according to the user's grip.However, in order to prevent too much or too little rotation, a lockingmechanism is important. Locking mechanisms are often pivotally connectedto a handle and spring-based to engage in the locking recesses in orderto turn a handle into various operating positions. Locking mechanismsnot only give rotational handles stability, but may also providesecurity, which is very important for safe tool operation.

The ease of using this hand tool enhances power application by creatinga favorable angle between the ground and the point of entry of the handtool into the ground to allow a user to perform operations with lesseffort. The utility hand tool of the invention disclosed herein isdesigned for people who have different opening angle between their palmand arm, as the difference can vary between 75 to 180 degrees. In fact,the design of the handle itself and the handle relative to the rest ofthe tool can greatly impact the power application of the hand tool.Specifically, the angulation of handles may be necessary for tools tomaintain a straight wrist in order to prevent injury and to improvepower applications. The handle should reflect the axis of the grasp,which is generally 78 degrees from the horizontal, and should beoriented in order that the eventual tool axis is in line with the indexfinger.

Optimum tool angle depends on the posture of the user. The amount oftorque and force that can be exerted also depends on the workingposture. For example, repetitive screw driving should be done on ahorizontal surface above the elbow, and push or pull should be done inthe direction of the forearm, with the handle directly in front of it.Therefore, the ability to change the angle of the hand tool can be ofgreat importance in providing for more torque or force and to minimizeor eliminate injury and discomfort.

Notably, the present invention is suitable for utility hand tools forboth left-handed and right-handed individuals. The preferred hand, alsoknown as the “dominant hand,” is the right hand for about 90% of thepopulation and the percentage appears constant across cultures and forboth sexes. Non-preferred hand tends to have approximately 94% of thegrip strength of the preferred hand. Thus, for a hand tool that isusable in either hand, the ability to rotationally adjust the angle ofthe hand tool allows for the hand tool to adapt to the users' hands whenthey switch hands rather than having the users' hands adapt to the tool.

As an example, when holding a bow saw, many users have found that whentheir hand and grip is at a 90 degree angle as opposed to holding ithorizontally as with regular bow saws, the pushing and pulling of thebow saw is much more effective when the user is able to turn the handleto the 90 degree angle. At the optimal angle and with a better grip, theuser is able to produce a much larger force while placing less stress onthe arm and hand of the user. This angle may be different for everyindividuals, but since the handle can be adjusted, each individual usercan adjust the handle to their optimal angle to prevent injury whilealso improving their productivity.

The axis of the grabbing means 130 for manipulatingthe rotational handle 105 may be perpendicular to the axis of theconnector 115. The pin 1200 and the spring 1201 is secured to theconnector housing 300 through the pin securing hole 1202. The pin 1200and the spring 1201 provide the rotational handle 105 with the mechanismto be rotated and adjusted according to the need of the user. There aremultiple sink holes 1203 on the grabbing means 130 for providing alocking mechanism using the pin 1200 and the sink holes 1203. The pin1200 is sunk into one of the sink holes 1203 to lock in the desiredangle for the hand tool. The release mechanism 400 allows the pin 1200to be disengaged from the sink holes 1203, thereby allowing the handleto be rotated to the desired angle.

FIG. 14 is an illustration of a close-up view of the pin 1200 and sinkhole 1203 locking mechanism for that rotational handle assembly. Asshown, the pin 1200, secured in the pin securing hole 1202, is pushed bythe spring 1201 and is decompressed into the sink hole 1203. Bycompressing the spring 1201, the pin 1200 can be released from the sinkhole 1203, allowing the handle to be rotated to the desired angleaccording to the application of the hand tool.
